Bug 215636: java/openjdk8: Add fontconfig support
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=215636



--- Description ---
Created attachment 178350
  --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=178350&action=edit
patch file

Attached patch adds optional (unchecked by default) support for fontconfig in
OpenJDK FreeType scaler. This allows scaler to obtain per-family FreeType
rendering and loading flags from fontconfig instead of relying on OpenJDK
heuristics, which noticeably improves font rendering in Java appications.

Patch code is based on original OpenJDK Infinality patches from [1] (now gone)
and Fedora 21 [2].

Also attached are rendering examples with and w/o fontconfig patch:
